Introduction: YD-400B-type melt flow rate meter is in accordance with "GB / T 3682-2000 Thermoplastic plastic melt flow rate and mass flow rate measurement", "ISO1133-2005 Plastics-Determination of the melt mass-flow rate ( MFR) and the melt volume flow rate (MVR) and other standards designed and manufactured for the determination of thermoplastic melt flow rate of the instrument. With melt mass flow rate function; with automatic cutting device; with a mini printer print output melt mass flow rate test results; with FLASH memory, can store 20 copies of quality test results and can always refer to and print. The instrument has the advantages of simple structure, convenient use, accurate measurement, stable and reliable performance. The instrument is not only suitable for the test of engineering plastics such as polycarbonate, fluoroplastic and nylon with high melting temperature, but also suitable for the testing of plastic with lower melting temperature such as polyethylene, polypropylene, polystyrene, ABS resin etc. Widely used in plastic production, plastic products, petrochemical and other industries and the relevant tertiary institutions, research institutes, commodity inspection departments. Technical Parameters: Extruded part of the material Outlet diameter: Φ2.095 ± 0.005 mm The discharge port length: 8.000 ± 0.025 mm Loading tube diameter: Φ9.550 ± 0.025 mm Loading cylinder length: 152 ± 0.1 mm Piston rod diameter: Φ9.475 ± 0.015 mm Piston head length: 6.350 ± 0.100 mm Test load The test load is obtained by combining a set of weights and a piston rod assembly in different ways. They can form the nominal load required for the test, a total of 8: Level 1: 0.325kg = (Piston rod + weight tray + insulation sleeve + 1 # weight body) = 3.187N Level 2: 1.200kg (0.325kg + 2 # 0.875kg weight) = 11.77N Level 3: 2.160kg = (0.325kg + 3 # 1.835kg weight) = 21.18N Level 4: 3.800kg = (0.325kg + 4 # 3.475kg weight) = 37.26N Level 5: 5.000kg = (0.325kg + 5 # 4.675kg weight) = 49.03N Level 6: 10.000kg = (0.325kg + 5 # 4.675k weight + 6 # 5.000kg weight) = 98.07N Grade 7: 12.500kg = (0.325kg + 5 # 4.675kg weight + 6 # 5.000kg weight + 7 # 2.500kg weight) = 122.58N Grade 8: 21.600 kg = (0.325 kg + 2 # 0.875 kg weight + 3 # 1.835 kg weight + 4 # 3.475 kg weight + 5 # 4.675 kg weight + 6 # 5.000 kg weight + 7 # 2.500 kg weight Code + 8 # 2.915kg weight) = 211.82N temperature control Control range: room temperature ~ 400 ℃ Temperature fluctuation: ≤ ± 0.1 ℃ 8h drift: ≤ 0.1 ℃ Temperature gradient: ≤ 0.5 ℃ Resolution: 0.1 ℃ Error correction: two linear correction Feeding temperature recovery time: ≤ 4min Dimensions Length 290 × thickness 410 × height 630 (mm) 2.2 working conditions Room temperature 10 ℃ -35 ℃, no vibration around, no corrosive media.
